34.323 - Middle European Brachypodium semidry grasslands

Classification des habitats du Paléarctique (2001)

Description

Brachypodium pinnatum ssp. pinnatum or Brachypodium pinnatum ssp. rupestre facies of unit 34.322. Geographical subdivisions can be introduced by use of the fourth decimal digit of 34.322 in the fourth place of 34.323. Brachypodium-dominated facies may form in all the regional types of grasslands inventoried in unit 34.322 as a result of nitrification or of dominance of grazing over mowing. Such processes are accompanied by a drastic reduction in species diversity. South western grasslands of units H to K of 34.322 and 34.323 are, however, generally rich in Brachypodium even in the apparent absence of degradation processes.
